Jana and her friend bought 4 hamburgers, 3 orders of fries, and 2 milk shakes for $3 each. They paid for the food with $20. Which part of the equation represents the total cost of their items? Justify your answer. c = $20 - (4h + 3f + 6)
It should be (4h + 3f + 6) because that is the total of the hamburgers, fries, and shakes. The $20 is the bill they gave and when you subtract (4h +3f + 6) the result is the change the get back.
